The second generation BC-2000 intelligent battery charger is sophisticated, simple to use, smart, and safe. The charger features four independent channels that can be programmed as group or individually, and six independent temperature sensors to protect against overheating.

The BC-2000 can also revive spent rechargeable batteries, or recondition batteries that have not been used for a long period of time, restoring them to their rated original capacity. In addition, batteries can be tested for present capacity and end of life.

Basic Features

The BC-2000 charges and discharges NiCd or NiMH rechargeable batteries. The BC-2000 provides four independent charging slots for AA/AAA rechargeable batteries. This package also includes 2 C and D size adapters. In addition, the charger can also optimize and test the maximum capacity of each rechargeable battery.

The charger can also charge batteries of different sizes (AAA, AA, C and D), types (NiCd or NiMH) and capacities at the same time.

The charger integrates the voltage change over time, referred to as the "minus delta voltage", and automatically terminates charging.

When the battery is fully charged, the charger will automatically continue to provide a trickle charge. Trickle charging prevents the rechargeable batteries from being overcharged, and compensates for self-discharging of the batteries.

The charger also includes over-temperature protection, and will shut off the current flow to protect the rechargeable batteries and charger itself from overheating.

The charger features an easy to read backlight display.

This package includes a UL rated AC adapter and a DC car adapter for applications on the go.

Comprehensive Operational Modes

Charge Mode: The rechargeable battery is charged up to its maximum capacity. The charging rate (current) can be independently adjusted for each battery.

Discharge Mode The discharge mode reduces the "memory effect". The rechargeable battery is discharged to a preset battery voltage (0.9v). Once the discharge is finished, the battery will be charged at the pre-selected charging current. Discharge current is always half of the selected charge current.

Refresh Mode: A rechargeable battery is charged and discharged repeatedly to optimize to its maximum capacity. Old rechargeable batteries or rechargeable batteries that have not been used for a long period of time can be restored to their rated capacity. Depending on the selected charging current, it can take days before completed. The refresh mode will complete three discharge and charge cycles before completed.

Test Mode: The test mode checks the present capacity of the rechargeable battery. The maximum capacity is determined by discharging the rechargeable battery after fully charged. If the maximum capacity is much lower than the rated capacity then it may be near its end of life.

Quick Test Mode: The charger will analyze the dynamic internal battery resistance by applying a load current, and measuring the current.

Designed with Safety in Mind

The BC-2000 includes six independent sensors for comprehensive overheating protection. There are four independent over-temperature battery sensors and two independent over-temperature control board sensors.

Short circuit protection is designed on the main board. The charger will not be damaged, even when the battery is completely short circuited.

The rugged construction offers extensive ventilation for the batteries and charging circuits.
